Clip for book backs



April 15, 1930. F. s. SCHADE CLIP FOR BOOK BACKS Filed pril 9, 1929Patented Apr. 15, 1930 UNITED STATES PATENT OFFICE FRANK S. SCHADE, 0FHOLYOKE, MASSACHUSETTS, ASSIGNOR TO NATIONAL BLANK BOOK COMPANY, OFHOLYOKE, MASSACHUSETTS, A CORPORATION OF MASSACHU- our son Book BACKSApplication filed April 9, 1929. Serial No. 353,851.

This invention relates to spring clips, but especially has reference todevices of this sort that carry labels and are applied to the edge of abook cover back that has what is known as a tip, which is a thickenedpart of such edge usually formed by rolling over the material of thecover back at one or both edges at the top or bottom of the back.

The object of the invention is to provide a spring clip which whenapplied embraces the cover back and is shaped so as to conform over thetip on the inside of said back and likewise to fit the curvature of theoutside of the back with the label exposed.

In the accompanying drawings which form a part of this descriptionFigure 1 is a perspective view of the rear of the clip without thelabel- Figure 2 is a perspective view of the parts of the clip includingthe label, as they appear prior to assembly- Figure 3 is a perspectiveView of the assembled clip with label applied- Figure 4 is an elevationof a book back with the clip in position thereon, and

Figure 5 is a section at line 5-5 of Figure 4.

In the detailed descri tion which follows similar numerals of re erencewill be used to designate like parts in the several figures of thedrawing.

The main body portion of the clip is a skeleton frame 1 made of springwire bent into any suitable shape, preferably rectangular, with the endsof the wire at the bottom of the frame and bent into spaced upwardly andoutwardly curved terminals 2.

The wire at the top 3 of the frame is preferably curved to fit theconvexity of the outer surface of the cover back when the book isclosed, and the label 4 is creased and wrapped around the frame 1 withthe flaps of the label overlapping at the rear of the frame, and when soapplied the label cannot accidentally slip upwardly owing to thecurvature of the top wire 3.

6 is a tongue having an offset 7 which merges into a portion 8 that iscurved to CO1? respond to the terminals 2, and the side edges of thisportion are firmly clamped to these terminals, so that it will be clearthat the tongue will be normally positioned against the overlappingflaps of the label as shown at Figure 3, and also that when said tongueis moved rearwardly away from said flaps, the resiliency of the wirewill, when the tongue is released, restore the tongue to normalposition.

This tongue therefore functions to bind the label on the wire frame whenthe clip is not applied to a book.

The labels bear all sorts of insignia on their faces, dependent on thenature of the business in which the books are used, and old labels maybe stripped from the frame and new ones applied with great facility.

In applying the clip to a back cover 9 the tongue is merely forcedrearward and the clip pushed in with the back cover embraced between thetongue and the frame, the latter being on the outside face of said back,and when the offset 7 has passed the tip 10 at the edge of the backcover, the tongue will spring against the inner face of the cover so asto hold the clip firmly in position with the frame and label snuglyagainst the outer face of the cover, and the tip 10 will be housed bythe curved portion 8.

It will be noted that the spring functions of the tongue 6 are duesolely to the resilience of the wire frame and the peculiar manner inwhich the tongue is shaped and secured to the terminals 2.

What is claimed is 1. A clip for a book back, comprising a spring wireframe of general rectangular shape having its upper end curved to fitthe convexity of said back, the ends of the wire being at the bottom ofthe frame and curved upwardly and outwardly, and a sheet metal cliphaving its lower end curved inwardly and secured to said ends andadapted to engage the beaded edge of said back.

2. A clip for book backs, comprising a rectangular skeleton frame madeof a single piece of spring wire having its ends terminating at thebottom of said frame and curved upwardly and outwardly in spacedrelation, and a sheet metal upwardly extendto said 8. A construction asin claim 2 with the addition that the lower end of said tongue isprimarily curved to correspond with the curvature of said ends rior tothe securing of said 3 ton egiifixedrelatidnfln that 'sfid tdn gieh anwhiihinerges into the curved lower end.
